'How I Met Your Mother' Finale: 5 Loose Ends That Still Need Tying

The final slap of the slap bet has been delivered, dozens of random asides from the previous eight seasons have been addressed and the long-awaited introduction between Ted Mosby (Josh Radnor) and the Mother (Cristin Milioti) is mere hours away -- but How I Met Your Mother still has so many questions left unanswered.

3. Will we never see Robin Sparkles again?

One of the most beloved recurring gags in HIMYM history is Robin's alter ego: a Canadian pop princess who released a brief string of '80s friendly hits -- "Let's Go to the Mall," "Sandcastles in the Sand," "P.S. I Love You" -- before falling back into obscurity. Even though Sparkles made a subtle cameo in the penultimate episode -- did you hear the orchestral "Sandcastles in the Sand" as Robin walked down the aisle? -- there is still hope for some small revival. Thomas, Bays and Smulders have been coy throughout the season when many have happily doled out a definitive "no" to speculation.

4. How long has the ending really been set?

For better or worse, a big part of the HIMYM finale has been set since almost the very beginning. How will we know which part? It's been in a time capsule since 2006. Ted's future kids, played by the now-adult Lyndsy Fonseca and David Henrie, filmed a finale scene during the second season to get the pivotal moment in the can before the cast members aged too much. Only a handful of people knew what it involved, and it's been in some vault ever sense -- waiting for its finale reveal. What's actually said in the little time capsule will offer some insight into how long Bays and Thomas have had their plan.

5. What happens to the Mother?

This is the biggest one of all. Ted meets the Mother, that's for sure, but what happens after they have their two children is a big question mark. A February episode was very cryptic about the Mother's longterm prospects, mortality-wise. And though it hasn't been teased since, cast and crew have refuted theories that the Mother has been dead the whole time with varying degrees of "no comment." Is the Mother dead? And, if she is, does it really matter?
